HARVESTER.

Specification of Letters Patent.

Application filed March 6, 1909.

Patented Apr. 12, 1910.

Serial No. 481,578.

To all whom it may concern:

Be it known that I, EDWARD J nsonxn, a citizen of the United States, anda resident of Bellevue, county of Huron, and State of Ohio, haveinvented a new and useful Improvement in Harvesters, of which thefollowing is a specification, the principle of the invention beingherein explained, and the best mode in which I have contemplatedapplying that principle, so as to distinguish it from other inventions.

The present invention, relating as inclicated to harvesters, has regardmore particularly to machines for harvesting corn, sorghum or other likecrops that have more or less stalwart stalks. One successful type ofharvester adapted for the handling of crops of this kind is that shownin U. S. Patent N 0. 763,569, dated J une 28, 190 and the object of thepresent invention is the further improvement of the machine thereinshown, with a view both to render the same more readily adjustable tovarious conditions of service, and to insure the cutting of the stalksand their maintenance in an upright position in the stalk receptacle,preparatory to their being taken from the machine and shocked orotherwise disposed of.

To the accomplishment of these and related ends, said invention, then,consists of the means hereinafter fully described and particularlypointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawings :-Figure 1 is a plan view of a corn harvestingmachine embodying my several improvements; Fig. 9. is a side elevationalview of the same; Fig. 3 is a rear elevation thereof; and Fig. {L is aplan view of the lower portion of the stalk guide-way and certainaccessory parts.

The frame work of the machine comprises a platform or base A, ofrectangular shape pivotally supported about the axis of a truck Bconsisting of a transverse shaft 6 and two driving wheels 6 fixedlymounted thereon. Triangular side members A joined at the rear by asuitable cross piece a complete the frame structure, and form, inconnection with fingers a and inclined boards a laterally spaced fromthe sides of the base, guide-ways along which the stalks to be cat aredesigned to be received as the machine advances along the rows of corn.To the rear of each such guide-way, the base A of the machine isextended to provide a supplementary platform or table a, Figs. 1 and 4,for the reception of the stalks, as they are severed in the mannerpresently to be explained. The stalks thus received onto said table areprevented from falling off backward from the machine by pairs ofover-lapping resilient arms a disposed transversely of the guide-way andat different heights above the table.

Vertical adjustment of the entire frame with respect to the truck axis,about which it is pivoted, is secured by providing brackets a formounting the frame on the truck, said brackets having racks a thatengage with pinions upon the truck axle. (See Fig. 2.) By rotation ofpinions Z) variation in elevation of the frame may be secured, suchrotation being effected in familiar fashion by a worm-shaft b engagingwith worm b mounted upon said axle.

Suitably connected with the front end of the machine base are the rearportions of a pair of vehicle shafts C or equivalent draft connections,the angular relation of which to the machine base A is determined by alover a pivotally connected by means of a link a with the forward end ofthe base and directly pivoted to said shafts, so that by suitableadjustment of its rear end, the base in question may be tilted forwardlyor preserved horizontal to suit the varying condition of the stalksbeing cut. Such cutting is effected incidentally to the advance of themachine along the rows of corn, or other crop, by suitable cuttingblades A angularly disposed across the rear end of the guide-ways formedlaterally of the base on each side by the fingers a and a (see Figs. 1and l) in the manner previously described. This cutter does not differessentially from that illustrated in the patent of reference, and, asthere, I employ a screw shaft, or spiral conveyer D for feeding thestalks along the guide-way and onto the knife. This conveyer inclinesupwardly and rearwardly adjacent to such guide-way, its forward endbeing stepped in the forward end of base A and its rear end beingmounted in the cross bar a that joins the side members A of the frame.Rotation of such conveyors is derived from the truck B by suitablesprocket gear connections d with the truck shaft 6 through intermediatedriving shafts D and D such connection being controlled by clutches d onshaft D as will be readily understood. In addition to such inclinedconveyers D, I mount in the present machine, two other conveyers D thatare similarly in alinement with the guide-ways but which liesubstantially parallel with the base and ad jacent to the cutting bladesA The rear ends of said conveyers D extend into proximity withtransverse driving shaft D and are directly connected therewith bybeveled gears 03 Having thus described the general construction andarrangement of my machine, the manner of its operation may be brieflyindicated. The elevation of the machine base, controlled by adjustmentof the worm shaft 12 is adjusted to provide forv the cutting off of thestalks at the desired elevation.

It will be obvious that, owing to the location of the knife blades, anyangular adjustment of the frame base by tilting the same more or lesswith respect to the shafts, will not greatly vary the height of stubbledetermined by adjustment of the elevation of the base. Such tilting,however, will be efiective to lower or raise the forward end of theguide-ways so as to pick up, when necessary, stalks that are inclined orblown over. In fact such forward ends of the guide-ways can beapproached very closely to the ground should occasion demand. Whetherthe frame be thus inclined or not, the advance of the machine along arow will bring successive stalks in such row into engagement with theupper, inclined conveyer, the operation of which will be to raise suchstalk, or if vertical, to pass the same along practically withoutdisturbing it. Similarly the lower conveyer comes into play, as themachine proceeds, engaging the lower portions of the stalks, and feedingthe same against the cutting blades. Their severance from the stubble ishence assured, and as the cut off ends are deposited upon the platform aconstituting the bottom of the stalk receptacle, the upper conveyersimilarly discharges their upper portions into such receptacle. Removalfrom the receptacle is secured by simply gathering in the arms thestalks that have accumulated therein, and then withdrawing the same, thespring holders a opening outwardly under such circumstances, althoughnormally effective to retain the stalks against accidental dischargefrom the receptacle.

It will thus be seen that, without sacrificing the simplicity ofstructure characterizing the earlier machine, I have provided severalhighly useful adjustments rendering such machine more readily adaptableto the varying requirements of different field condi l tions. At thesame time, by the provision of the auxiliary feeding means, specificallyconveyers D not only is the even advance of both the upper and lowerportions of the stalks onto the stalk receptacles assured, but suchconveyers directly cooperate with the cutting blades to sever thestalks. By extending the rear ends of the conveyers beyond the blades,as shown, they further serve the important function of pushing back thebutts of the stalks after they have been severed, thus acting as a sortof packer and permitting the storage of a greater number of stalks inthe stalk receptacles before it becomes necessary to unload the latter.The butts are obviously at the same time kept away from the knives afterbeing cut ofi. Finally the resilient arms a provide an extremely simple,yet effective, arrangement for removably holding the stalks 5 in suchreceptacles.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any one of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as myinvention 1.
